Pill Overload: 5+ Meds Spike Older Adult Death Risk

A recent study published in the Journal of the American Geriatrics Society has identified a significant mortality risk for older adults who take five or more prescription medications daily. This practice, known as polypharmacy, is a growing concern within aging populations. Researchers from the University of Michigan School of Medicine analyzed national survey data from nearly 7,828 individuals aged 65 and older. Participants' medication use was verified through direct inspection of pill bottles. The study followed these individuals for an average of 8.5 years. After accounting for underlying health conditions, taking five or more prescriptions was associated with a 38% increase in overall mortality risk. Furthermore, each additional medication taken was linked to a 7% increase in the risk of death.

Experts note that individuals on multiple medications often have more complex health issues, which can also contribute to mortality. The study's findings highlight the importance of "deprescribing," the process of carefully reducing or discontinuing unnecessary medications. However, the researchers acknowledge study limitations, including the exclusion of those in nursing homes and the lack of tracking for evolving health conditions over time. Medical experts advise individuals taking multiple medications to periodically consult with their physician or pharmacist to review each drug's necessity and dosage.
